To be honest, i don't know how to figure that out exactly. but i think it's 3.0 since it's colored blue as described here http://answers.yahoo.com/question/index?qid=20110606234231AAf9p5B

The Hard drive has dual functionality. It works for both usb 2.0 and 3.0. It just works more efficiently with 3.0.

It is a USB 2.0 A/B cable. I believe ONLY the 2.0 version works for this item.

Don't know for sure. I assume it is a clerical error on Amazon's part - associated wrong box image with the wrong product.If you look up the item number on LaCie's site, it says it is a USB 3.0 model.

It's a USB 3.0 put I would look for other options. SanDisk makes a great one. I just had my second one of these fail already... The first failed after 1 month, and the replacement lasted maybe 5-6 weeks. Extremely frustrated with the quality of the unit.

USB 2.0 needs a 2.0 cable, 3.0 needs a 3.0 cable. A 2.0 cable is USB on either end. The 3.0 has one USB and one MiniUSB connecting to the hard drive. They are not compatible. Please note about this hard drive, that it does not come with a US power cord/adapter. While in the manual it does show one, in the actual package I was bummed to find I didn't get one.(I bought one at the local radio shack)

Are you getting any USB 3.0 devices recognized as 3.0? If not, then you may need to ensure you have the correct USB drivers installed.

Yes, it works perfectly with any usb 2.0 port, it just doesn't run as fast as a 3.0

If you have 2 ports for connecting USB devices version 2.0 and one USB 3.0 port for use as internal storage or hard disk reading

I am not sure I understand your question...but this device works best with USB 3.0.

The USB end is NOT a 3.0. I cannot be sure it is not a 1.0. Shortly after I left my high review, I started using the device on a different computer, and it failed to work at all. I subsequently bought a different adapter from Amazon made by Plugable; it has worked well in all environments I have tried.

it should work with a USB 2.0. to figure out if it is a 2 or 3 you have to go to the control panel and look for the ports. right click on the port you are using and click properties. if your computer is more than a year old chances are it is a USB 2.0. the difference between the two is speed of transfer with 3.0 being faster.

Yes it will work in a USB 2.0 port, however you will only get USB 2.0 speed out of the drive when it is used in this way. To get 3.0 speed, the drive must be plugged into a 3.0 port.

I think there's one very important point that no one has mentioned: USB 3.0 provides 0.9 amps while USB 2.0 provides 0.5 amps. Keep that in mind. BTW, 3.5" always needs the power adapter; 2.5" USUALLY (not always) is not required.

USB 2.0 can be used with USB 3.0 slots, you just won't get the transfer speed.

My similar drive (5TB) is also equipped for USB 3, but it works great on my 2.0 ports. I assume it could transfer faster on 3.0, but there's no incompatibility.

USB 3.0 is newly developed with slightly different connector. USB 2.0 is 60 mb/sec (35-40 typical) data rate , high-speed, whereas 3.0 is 625 mb/sec (400 mb/sec typical) data rate, superspeed. USB 2.0 has 4 wires plus braided outer shield, 3.0 has 10 wires plus braided outer shell. The wire included is USB 3.0 on one end (device) and a USB 2.0 on the other (computer). Data rate I suspect will be limited to USB 2.0 data rate. For full USB 3.0, you would probably need cord with USB 3.0 on both ends and computer with USB 3.0 socket.
